Subject[PATCH 5.4 199/408] powerpc/pseries: Fix missing of_node_put() in rng_init()
Date
From: Nicholas Mc Guire <hofrat@osadl.org>

[ Upstream commit 67c3e59443f5fc77be39e2ce0db75fbfa78c7965 ]

The call to of_find_compatible_node() returns a node pointer with
refcount incremented thus it must be explicitly decremented here
before returning.

Fixes: a489043f4626 ("powerpc/pseries: Implement arch_get_random_long() based on H_RANDOM")
